Application filed November 21, 1901. Serial No. 83,131. (NomodeL) A To all whom it may concern: 7

Be it known that 1, WILLIAM GORMAN, a citizen of the United States of America,residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements inj I-I eating-Furnaces,of which the following is a speci-' fication, reference being had therein to the accompanying drawings. Y h

This invention relates to certain new and useful improvementsin heating-furnaces,an d relates more particularly to that class wherein natural and artificial gas are employed for fuel.

The object of the present invention is to provide a heater that will be extremely simple in its construction, strong, durable, and comparatively inexpensive tomanufacture; furthermore, one that may be readily taken apart and set up inproper position. i With the above and other objects in view; the invention consistsin thenovel combination and arrangement ofparts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification,and wherein like numerals of reference indicate corresponding parts throughout the several views, in which i Figure 1 is a side elevation of my improved furnace. Fig. 2 is a vertical sectional view thereof. Fig. 3 is a top plan view of the same. Fig. 4 is a-vertical sectional view of a portionof the outer casing, the conubustion-chamber,v

radiator-pipe, and hot-air pipes. Fig. 5 is a top plan view of the removable base-plate.v Fig. 6 is a top plan view of the furnace as shown in Figs. 1 and 2 of the drawings, with. the head of the casing removed therefrom.

The reference-numeral 5 represents a removable base-plate, having formed therein near itsouterend an annular recess 6 for the reception of the outercasing'7, said casing being provided with a watenreceptacle 8, extending into the casing ,7, said water-receptacleibeing provided with ahinged cover. 9, attached at- 10 to the outer face ofthe casing 7. The portion extending into the casing? has an open top to allow-the evaporation of the water. I "j The reference-numeralll represents a hood carrying an inwardly extending annular flangel2, forming an annular space between said flange, and the outer wallpf said hood, in which is seated-the upper end of the outer casing 7. cone-shaped top 14,-which extends into the hood proper and formsa spreader or deflector, the inner walls of-which are in 'closeproximity to the hot-air outlets 15, formed in the hood, said hot -air outlets communicating with thedistributing-pipes 16, whichlead to the different apartments to be heated. The reference-numeral17 represents agassupply pipe extending into .the'cone-shaped mixer-18,,which is formed at the lower' end of the burner 19, said Journer being preferably rectangular-in form and'havinginclinedsides terminating in the flange 20, said; fla nge engaging the underface of; theremovablebase 5, said base-plate 5 havinga' central. opening 21 formed therein, through -whiclpthe upper end of the burner extends. a The said burner The said hood carries an inverted-v 19 has formed therein a seriesof openings 22,

I le'adinginto the combustion-chamber 23. At. the upperfend of said burner are inwardlyextending walls2, which likewise form the deflector, as will-be readily understood.

Thereference numeral 25 represents a grate or basket', which is preferably rectangular in form and is adapted to receive the refractory material 26, said grate or basket being rigidly secured in any suitable manner to the upper face of the burner.

inner casing 27, said cylindrical innerjcasing being seated at its lower 'endin theanmiiar recess 28, formed in the upperface of theiremovable base-plate, the said annular recess being in close proximity to the central opening 21 and extending upwardly into the radiating-pipe 29, the upper end of said cylin- The said combnstion-chamber 23 is formed by'thecylindrioal drical casing being provided with a deflector 30. The opening 31 is formed in the upper portion of the cylindrical casing 27 to communicate with the radiator-pipe 29, said pipe extending through the outer casing 7 ,as shown at 32, and leading to the flue or chimney. (Not shown in the drawings.)

The reference-numerals 33 indicate airpipes, which are seated between the flanges 34, formed on the upper face of the removable base-plate, said air-pipes communicating with the series of openings 35, formed in the removable base-plate and communicating with the cold-air inlet. These airpipes 33 are of greater diameter at their lower ends than at their upper ends, and their walls gradually extend at an angle inwardlyin order to check the direct draft and retard the currents of air to permit the same to be heated in their passage through the. heater.

The reference-numeral 36 represents a cylindrical opening formed in the outer casing, extending through one of the air-pipes and into the combustion-chamber for the purpose of forming a hand-hole to permit the ignition of the gas, this cylindrical opening 36 being provided with a door 37, which is hinged at 33, said opening being normally closed to prevent the heat from escaping through this outlet.

The operation of my improved device is as follows: lVe will assume that the gas has been ignited, which will heat the grate or basket retaining the refractory material, which will serve to retain the heat and assist in producinga larger number of units of heat, it being a well-known principle of physics that the heat will concentrate,and as the latter rises the deflector 30 will serve to deflect the heat toward the inner walls of the cylindrical casingformingthe combustion-chamber. The burned gases will then escape by the way of the opening 31, and by means of the circuitous course of the radiating-pipe 29 the draft will be checked, and the pipe 29 will then serve a double purpose of conducting the burner-gases and fumes and, furthermore, produce a larger heating-surface than could otherwise be obtained. By reason of the peculiar construction of the air-pipes 33 the air will be thoroughly heated from the combustion-chamber. The heated air will then be conveyed through the conducting-pipes to the various compartments.

It will be noted that by reason of the deflectors 14, 24, and 30 the heat will not only be deflected and an equal distribution of the same obtained, but will also be baffled, thereby obtaining advantages that will be readily apparent in this class of inventions.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a heater, the combination of a base having formed therein an annular recess, a cylindrical casing seated in said recess having formed therein an air-inlet, a removable base arranged above said casing having formed therein a series of openings, a burner secured in said removable base, an outer casing secured above said casing, a water-receptacle extending into said outer casing, an inner casing forming a combustion-chamber, a deflector arranged at the upper end of said inner casing, a radiating-pipe communicating with said combustion chamber arranged above said inner casing, a removable hood, a deflector secured at the upper end of said hood, a series of distributing-pipes communicating with said hood, all parts being arranged substantially as described.

2. In a heater, the combination of an inner and outer casing, a series of tapering airpipes arranged around said inner casing, a burner, a grate or basket secured to the upper face of said burner, refractory material arranged in said grate or basket, a deflector arranged at the upper end of said inner casing, a radiating-pipe communicating with said combustion-chamber, a suitable hood, and a series of distributing-pipes extending from said hood, substantially as described.

3. In a heater, the combination of a suitable support having formed therein an annular recess, an annular casing seated in said recess having formed therein an air-opening, a removable base-plate arranged to support said casing having formed therein a series of openings, a burner arranged in said baseplate, a deflector secured in said burner, a grate having arranged therein refractory material secured above said burner, an inner and outer casing, a series of tapering airpipes arranged around said inner casing, a deflector secured to the upper end of said inner casing, a radiating-pipe secured upon said inner casing and communicating therewith, a hood carrying a deflector, and aseries of distributing-pipes connected to said hood, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

WVILLIAM GORMAN.
